abstract = {The deep-seated spontaneous coal-seam fire occurred in the southwestern part of the Upper Silesian Coal Basin (S Poland), confirmed by oxygenated compounds emission to over- and underlying rocks. The fire was dated at 19.2–19.8 Ma using the 39Ar-40Ar method and palaeomagnetism. It was initiated in the Carpathian foreland thanks to a normal faulting in response to thrust-loaded deflections of the Carpathian foreland lithosphere during collision of tectonic plates (Alcapa and stable Europe). The orogenic loading caused this normal faulting in the foreland and triggering the flexural mechanism of foredeep subsidence and forebulge uplift. Thanks to the dating of rocks affected by the spontaneous coal fire initiated during the rapid uplift of coal-bearing rocks, when they became exposed to the aeration zone, the age of these mountain-building processes in the Carpathians has been precisely defined. © 2022 John Wiley & Sons Ltd.},

abstract = {Coal seams in the Upper Silesian Coal Basin vanish within the Carboniferous Upper Silesian Sandstone Series and below an unconformity marking the Carboniferous top surface. Changes in the geochemical, mineralogical, petrological and palynological characteristics of gangue rocks associated with the vanished seams record what happened. The observed changes could have been caused by (1) coal-seam paleofire, (2) peat combustion, (3) igneous intrusion, (4) metasomatism and/or (5) weathering. Multifaceted research on samples collected at the Jas-Mos mining area, a part of the operating Jastrzębie-Bzie Coal Mine that are representative of different geological settings in the northern and southern parts of the mining area, point to intra-deposit paleofire as the most plausible reason for the disappearance. Biomarkers enabled recognition of differences in heating duration and oxygen access. Coal seams in the south burned quickly with abundant oxygen supply. Seams in the north pyrolyzed for an extended time under conditions of limited oxygen. Though other methods used proved less sensitive, all confirmed low (100–150◦C) paleotemperature heating. Overall, the reason for the local disappearance of the coal seams, making their exploitation difficult and unprofitable, can be assigned to a variety of different processes in a complex overlapping history of variable weathering, heating due to local endogenic fires and, probably, earlier peat combustion. © 2021 by the authors.

abstract = {The impact of natural intra-deposit heating on the δ13C signature, organic geochemistry, and petrology of coal and coal-bearing rocks characterised by various degrees of coalification and palaeoenvironments in the Upper Silesian Coal Basin, Poland, is elaborated. Reconstruction of palaeofire performed by heating experiments up to 400 °C in open and semi-closed systems with different heating regimes confirms the crucial significance of temperature and oxygen access. In open-system heating, released 13C-depleted gases enrich residue coke in 13C compared to raw coal. Petrological examinations did not show the impact of palaeofires on the maceral properties of coal. However, the carried-out experiment caused the formation of devolatilisation pores, rounded edges, cracks, pale rims, as well as higher reflectance and paler colour that was what was expected. Extractable compounds become highly depleted, and low-weight organic compounds nearly absent. Relatively high contents of combustion-formed PAHs are an indicator of open-system heating. In semi-closed systems, the final total isotopic composition was almost unchanged as no components are carried away though changes in petrography and geochemistry occur. Increased extract yields reflect the release of bitumen from closed pores and partial pyrolysis of organic matter. Depletion of lighter n-alkane compounds, total carbon TC and volatiles decrease, and variable values of various alkyl aromatic hydrocarbon ratios are also indicative of semi-closed heating. Coal seams suspected of intra-deposit heating show geochemical and isotopic features similar to semi-closed- rather than open-system heating, and their δ13C signatures and organic geochemistry did not respond strongly during laboratory re-heating. © 2021 Elsevier B.V.},

abstract = {Landslides are one of the most prominent processes degrading the Beskidy Mts. slopes. Susceptibility assessment is based on the detailed mapping of the Dukla commune (235 km2) at the scale 1:10,000 in frames of the project Landslide Counteracting System. The terrain affected by landslides is 19.59 km2, which is 8.34% of the researched area. The largest number of landslides can be found in the Beskid Dukielski Mts. area, where nearly 78% of all landslide areas are concentrated. Analysis of landslide-causing factors was performed using the index of entropy method. The following five factors were considered: lithology, slope inclination, slope aspect, distance to faults, and distance to drainage. The most important role in the development of mass movements in the study area is played by slope inclination (0.0079) and lithology of siliciclastic flysch (0.0066). The method applied also contributed to devising a landslide susceptibility map of considerable accuracy at 90.5%. The analyses of the landslide factors have proven that understanding of geology and landforms is not only of cognitive significance, but adds to practical applications in spatial management. The studies confirmed usefulness of large-scale mapping of landslides and applying statistical methods and GIS techniques in the spatial analysis of landform transformations. The obtained landslide susceptibility map can be a basis for assessing landslide risk. High and very high landslide susceptibility classes cover nearly 50% of the study area. © 2016, Polish Geological Institute. All rights reserved.},

These structural surfaces of different age, present in the top surface of Carboniferous deposits of the Upper Silesian Coal Basin, were investigated in morphotectonic research. Discordances in the morphotectonical record separate older faulted and folded Carboniferous deposits from younger, nearly subhorizontal rocks of epi-Variscan cover. This polychronic and polygenetic geological heterochronous boundary of the top surface of Carboniferous deposit consists of the following coeval discordances: sub-Permian, sub-Triassic, sub-Jurassic, sub-Cretaceous, sub-Miocene and sub-Quaternary. Those buried erosional surfaces with ancient landforms were some formed by terrestrial, others by marine planation. The repeated erosion of Carboniferous deposits and sedimentation of covers as well as fault, monocline and fold-flexure deformations are reflected in differentiated configuration of discordances in the height range from about 400 m a.s.l. to 6000 m b.s.l.},

In the coal-bearing deposits, humic gels have been the natural barrier and made the hydrocarbon reservoir, traps and seal of the elementary carbon. The coalification process was interrupted by faulting of the coal-bearing deposits, followed by fast geothermal cooling.

abstract = {In 1994 year exactly 150 years past since the first large-scale (1 : 50 000) geological map (geognostic) of the Upper Silesian region (Carnall, 1844) had been published. Since that time about 30 different geological maps of this region has been published in scales from 1 : 300 000 to 1 : 25 000 (Czarnocki, 1935). The large scale maps (1 :50 000 and 1 : 25 000) and geological atlases (1 :100 000) contained from a few to tens of series sheets (vide Figs 1, 2). Most of those maps were treated as secret or confidential documents thus they were unknown for foreign geologists. Cartographic-geological works carried out on the Upper Silesian Coal Basin (USCB) can be divided into three main periods (Lewandowski et aL, 1995). The first period - the pioneer one includes the 19th century and the beginning of the 20th century (to 1913). The Geognostische Karte von Ober-Schlesien in scale 1:100 000 (Roemer, 1870) and Geological Atlas of Galicia, of which three sheets: Oświȩciin, Chrzanów and Cracow were worked out by Zarȩczny (1894), made the most remarkable achievement in geological cartography of that period. The Upper Silesian sheets of Geologische Karte von Preussen, published in scale 1:25 000 (Fig. 2) by Assmann, Cromer, Michael, Tornau, Quitzow, Range (1913) deserve special distinction. Geologische U″Übersichts Karte des Oberschleshchen Steinkohlenreviers..., supplemented with synthetic work Die Geologie des Oberschlesischen Steinkohlenbezirkes (1913) was the regional recapitulation of the USCB geological mapping of the first period. The second period (1935-1972) was a continuation of detailed and synthetic regional works. Doktorowicz-Hrebnicki was the main cartograph of that period, together with a team of geologists mapping the eastern part of the USCB. Unfortunately, most of the large scale geological-cartographic elaborations of that time was not published, because of the secrecy of geological data. These were mainly structural maps of coal-bearing Carboniferous and others different types of documentation maps of mines. In the post-war period (1955-1995) most of geological-cartographic elaborations were limited only to the modification of already existing, large scale maps, and in case of need to regional synthesis construction, on maps in scales 1 : 100 000 and 1: 200 000; apart from Doktorowicz-Hrebnicki cartographic work being the only exception from the rule. Sketch Geological Map of Poland, sheet Cracow in scale 1 : 300 000 by Doktorowicz-Hrebnicki and Rozycki (edition A - 1948 and B -1955) was the recapitulation of cartographic elaborations as a regional synthesis. This map made the grounds for further editions: Sketch Geological-Engineering Map (1955), Sketch Hydrogeological Map - A (1963) and B (1969), and Sketch Map of Rock Resources (1964). The Hydrological Map of the USCB, in scale 1 : 100 000 (1963) was also elaborated on the base of geological maps of Doktorowicz-Hrebnicki. In 1955-1960 almost the whole area of the USCB was covered by several sheets of Detail Geological Map of Poland in scale 1:50 000. These maps were elaborated availing the possibility of modification of the existing, geological maps. Unluckily they kept a part of geological data in secrecy in relation to originals, and were considerably simplified as well. Next years fructified with the elaboration of lacking sheets, and nowadays only the southern part of the USCB is devoid of the detailed geological mapping (Fig. 2). Within Geological Map of Poland in scale 1 : 200 000, two sheets of the USCB appeared: Gliwice (1979) and Cracow (1980), which gave the opportunity to the next regional synthesis. The map just mentioned contains two editions A - a surface map and B - a map without Quaternary deposits, both with an explanatory text and general data (colourless sheet maps in scale 1 : 50 000). As a result of Geological Atlas of the USCB in scale 1 : 100 000, elaborated by Polish Geological Institute, a few maps of great worth were printed. In the early 80s two maps were printed: Geothermal Map and Map of Coal Quality, in 1980 and in 1983 respectively. In 1994 the Structural Map of Carboniferous was printed and in 1995 Geochemical Atlas of the USCB in scale 1 : 200 000. All of them are sketch maps and of regional synthesis type. The Upper Silesian Coal Basin acquires over 200 geological documentations of different type. The mining areas posses hand-written maps (in scale 1 : 25 000 and 1 : 5 000) of the whole USCB. Apart from a large number of maps and elaborations, the region is still lacking in a complex detailed geological map in scale 1 : 25 000. Such map would enable full utilisation of the existing documentation and comprehensive presentation of complex geological ore deposits and geognostical problems of the USCB.},

abstract = {Miocene basement is marked as an erosional discordance between the rocks of the epi-Variscan Middle-European Platform and the Miocene molasse of the Carpathian Foredeep. Erosional-denudational and fault forms with denivelation about 1000 m are visibly marked in the sub-Miocene relief. There is poly-ordered valley network contain from different kinds of the valleys from a simple V-shape valley to flat-bottom with a canyon profile (Szeroka paleovalley) and concave-bottom ones. Structural control of the relief testify to cutting a plateau and ridge denudation surface is a relic of this process. A few stages may be subdivided in geomorphological development of the Miocene basalt surface. -from English summary},

abstract = {Geological units differentiated in the course of geological mapping are characterized on the basis of 150 granulometric analyses. For example, till from southern Gozdnica region is sandy-gravel, with polymodal grain-size distribution and it represents bottom moraine, whereas that from the northern region is sandy, with unimodal, flattened grain-size distribution. Three granulometric types of fluvioglacial sands and gravels are differentiated. Sands and muds of the Kwisa ancient valley are characterized by symmetrically steep distributions with modal class of 2phi. The methods of granulometric analyses appeared insufficiently sensitive to show differences in origin of deposits made similar to one another by repeated reworking under different sedimentary conditions in the Gozdnica area. -from English summary},
